A film and a process for its production includes a light-permeable replication lacquer layer with a diffractive relief structure formed in a first side of the replication lacquer layer, a light-permeable color lacquer layer, formed only in areas, arranged on the relief structure, and a reflective layer, formed at least in areas, arranged on the first side of the replication lacquer layer. In areas of the film where the color lacquer layer and the reflective layer overlap, the color lacquer layer is arranged between the replication lacquer layer and the reflective layer.

Film and method for producing same

The invention concerns a process for producing a high-resolution surface pattern on a substrate and a multi-layer body produced by means of that process and an apparatus for carrying out the process. A printing substance is applied in pattern form to the substrate by means of a printing process. For fine structuring of the surface pattern, prior to application of the printing substance, a microscopic surface structure with a plurality of grooves is replicated into the surface of the substrate. The fine structuring of the surface pattern is determined by the respective locally applied application amount of printing substance and the respective local relief parameters of the microscopic surface structure in particular orientation direction and profile shape.
